Which space heater should you buy? Four questions

This tool scores the European models from our Italian and Spanish editions (230 V). If you shop on Amazon.com, the short answer from our US guide is the Lasko 754200 for a bedroom or home office, the Lasko CD08200 for the bathroom and the De'Longhi EW7707CM oil-filled radiator for long evenings. The four questions below explain the logic behind each pick.

How we chose the questions

The quiz weighs four things. The room, because a bathroom needs a heater the maker lists for that use, such as one with an ALCI plug, and a living room needs more reach than a bedroom. How long it runs: for a quick half hour a fan heater wins, since it starts and stops instantly; for hours at a stretch an oil-filled radiator, slower but steadier. Noise, because every fan heater hums while a radiator only clicks when the thermostat kicks in. And budget, which is a hard filter: anything above the tier you pick drops out. We don't treat "energy-saving" as a separate criterion, because every electric heater turns the same energy it draws into heat; what changes your bill is the thermostat and a heater sized for the room.

How the score works

Each answer gives 2 points to the product that is ideal for that profile, 1 to an acceptable one and 0 to one that does not cover it. Budget is eliminatory: anything above it is out. Ties go to the guide's order. Amazon links are affiliate links, but the result does not depend on the commission.

Frequently asked questions

Do "energy-efficient" space heaters really use less power?

Not for the same heat output; you spend less with a thermostat and a setting sized for the room.

Can I leave a space heater on all night?

Manuals say not to leave it running unattended; warm the room before bed, then switch off or use a thermostat-controlled model.

What kind of heater is safe for a bathroom?

One the maker lists for bathroom use, such as a model with an ALCI plug, placed with the clearances in the manual.
